Helping Communities Grow

Our passion is for bringing beauty and grandeur to the Connecticut coastline. Whether that means updating homes back to their original splendor,  building new custom homes or doing remodels, we aim to stay true to the neighborhood and create a structure that complements the community.


We work with a team of expert subcontractors and local developers, and strive to develop good relationships with town officials, and all necessary governing bodies.


We use and teach traditional methods within the trades, while simultaneously keeping up with new products, building sciences and niche installation practices.


We deliver what we promise, and we take pride in what we have built – and in making our customers happy. We maintain exacting standards in order to create homes that last.

From Our Clients

We have had the pleasure of working with Dan and his crew many times over the years. Simply put I will never use another contractor for any work on my house other than Dan! He has done both large and small jobs at our house and all have been done with great skill and professionalism. He stands by his work 100%. He is honest and fair regarding how much things will cost and willing to work with us to help decrease costs when able…His work is impeccable. The addition he put on is a lovely handicap-accessible master bedroom and bathroom and a beautiful library with built-in bookshelves floor to ceiling with a rolling latter. It is truly beautiful.

I first hired Dan and Aschly to perform a complex addition at our office building. Their work was far superior to the original builder. Great crew, great attention to details and timely. About a year later, I had them add a conference room and foyer to the same building. Another excellent job and the place looked fantastic. All our customers were impressed. I enjoyed working with them so much that I hired them to add a large living room and sun room wing to my home in Willington as well as a full renovation of the existing structure. Dan has excellent problem solving skills and managed to overcome supply chain issues to get the job done in an artisanal fashion. You won’t find a better contractor to work with in CT. Many thanks Dan and Aschly and rest of the crew at Constanza & Company!

We are so excited to have them build our new home in Stonington. It will be a tear down and rebuild at Lord’s Point. They have been “hand holding” us during this whole process! Being a local realtor I have recommended them to my clients that have loved their work and stayed within the timeframe they agreed to!
